In many disciplines there are professional maturity models. Sometimes they apply to an organization (see Capability Maturity Model for Software) and sometimes they apply to individuals (see the work done for architects done by Bredemeyer Consulting). In both cases, they trace the progress from an early development stage to a fully mature stage. The greater effectiveness comes as one moves toward the latter stages.

I have not seen such a formal maturity model for strategy leaders though I can infer one from my experiences. Here are the 5 stages that occur to me with some characteristics. What do you think?
